10 things what vitamin C can do for your skin

Of the many active ingredients I’ve tried, vitamin C works best for me. It was first introduced to me by a dermatologist and ever since, I’ve always had good results using products formulated with the ingredient. I believe many of you are also fans of the ingredient and so I hope this list of 10 that I’ve compiled on what vitamin C can do for your skin will interest you.

1. A topical vitamin C product is helpful
Although vitamin C is found at high levels in both the dermis and epidermis, it is higher in the epidermis than the dermis (source). So using a topical vitamin C product is beneficial to replenish and plump up the epidermis.

2. Vitamin C limits the damage induced by UV exposure
While vitamin C is not a sunscreen, its antioxidant properties protects against UV induced damage caused by free radicals. In fact, the vitamin C levels of the skin can be severely depleted after UV exposure, and so it’s good to replenish the vitamin to our skin (source).

4. Exfoliation enhances absorption of vitamin C
Because the stratum corneum (outermost layer of skin) is the primary obstacle to efficient vitamin C absorption from external sources, removal of the stratum corneum by laser, chemical, or mechanical methods such as exfoliation enhances absorption (source).

5. Effective topical vitamin C products can irritate sensitive skin
It appears that vitamin C absorption greatly depends on pH. Study shows that L-ascorbic acid must be formulated at pH levels less than 3.5 to enter the skin (source). This is why the ingredient can be greatly irritating to sensitive skin.

6. A high dose of vitamin C is not necessarily more effective
A high dose of vitamin C in a product may not be necessarily good. In fact, studies have shown that maximal absorption was achieved with a 20% vitamin C solution, with higher concentrations showing lower absorption (source).

7. A good vitamin C ingredient can oxidize quickly
The stability of vitamin C in topical solutions is a concern, as exposures to air, heat, and/or light may slowly degrade vitamin C. Although the natural form of vitamin C, ascorbic acid, is the most effective for topical administration, it is the least stable in solution. However, stable synthetic derivatives, such as ascorbate phosphate, are considered to have limited permeability and function in skin (source).

8. Topical combination of vitamin C + E are more protective
While topical application of vitamin C reduces the damage from UVA exposure, topically applied combinations of vitamin C and vitamin E are more effective in preventing photodamage (source).

9. Oral vitamin C + E protect against UV exposure
Oral supplementation with vitamin C does help our skin somewhat but it is the combinations of vitamin C and vitamin E that have documented UV protective effects (source).

10. Dietary vitamin C reduces dry skin
Studies suggest that vitamin C, especially L-ascorbic acid, increased trans-epidermal water loss (TEWL) when applied and so it can be drying for the skin. However, this can be countered with oral consumption of the vitamin as higher intakes of dietary vitamin C have been correlated with a decreased risk of dry skin (source).

Vitamin C is definitely an essential for good skin health and like I’ve mentioned before, something to consider including in your skin care routine.

I guess I only found out lately that higher dose of Vit C applied topically doesn’t really make as much difference, it just dries the skin. I’ve been experimenting with a DIY Vit C mask and because I’m too lazy to do some measurements, I think I’ve been overdosing on Vit C — and I couldn’t really see as much difference compared to previously, when I was using exactly a 15% ratio.Eco Beauty last post is: Review: ila Face Oil for Glowing Radiance could have very well been ‘Liquid Gold’

It was interesting to learn from you and other readers that vitamin C was drying for your skin. I’ve always been fine with it but I found out it’s definitely not good for my eye area. Anyway, I tried to be quite exact when I was using the DIY vitamin C serum cos I was worried of “side effects”.

This is a very informative summary about Vit C’s, loved it!! Although I did hear this rumor where people say it’s better to drink lemon juice during evening/night instead of in the morning as it can cause photosensitivity to the skin. I’d like to know if you’ve any comments on this hearsay? Coz I thought consuming Vit C in the day would be more beneficial and productive in terms of working or studying, like being more energetic; and yet I certainly want to do what I can to also protect my skin. Thanks 🙂

Interesting…I’ve not heard of that rumor as I’ve always been encouraged to drink it in the day. I agree about the energy bit you mentioned. Plus, through the sources I’ve read, vitamin C provides UV protection too, especially added with vitamin E. But I would think it’s best to use a sunscreen too. I would be more careful with application of vitamin C in the day though because I’ve read it causes photosensitivity although most dermatologists deny that.

Thank you for this eye-opening and informative article. I didn’t know that Vitamin C helps our skins to be in a better condition. I added this to my knowledge and I appreciated it. Do you think that we would better take Vitamin-C in the evening, rather than in the morning? Thanks again.Clair last post is: Natural Remedies For Puffy Eyes

Thanks for these interesting points. I use to be an acne sufferer, but now with that behind me, I’m always looking for ways to keep my skin smooth and hydrated and vitamin C is definitely one way of doing that.

I have sensitive skin and definitely appreciate the caution (#5) regarding using Vitamin C on sensitive skin. Thanks for sharing this important information.Suze last post is: How to Make Your Eye Lashes Grow

What an excellent article – I didn’t realise that vitamin C has so many benefits, and i certainly didn’t know that it can protect against UV damage..the cautionary words about taking too much dietary vitamin c are also welcome.

Yes, Vitamin C is very effective at combating UV damage and fighting free radicals that cause premature aging of the skin because it is chocked full with potent anti-oxidants. Vitamin C is also helpful in making the skin brighter and radiant.natoxtruereview last post is: Natox Review – The Truth You Need To Know!

Very helpful info Sesame… Thanks!!! I just read your response about being careful about applying Vit C to the eye area. I was applying an eye cream(can’t remember the brand name) with Vit C that I got at Costco ages ago and I’m wondering whether that may be the reason why I have some sort of tiny little bumps around my eye, looks like blemish…. I feel like they age me when I apply makeup around the eyes!!! What do you suggest I use???
Thanks,
T ^.^

Several years ago I too was introduced to a vitamin C serum from my dermo doc as well. I really liked using it but it was super expensive. I didn’t know much a lot about it other than it was really healthy for your skin – but now you’ve shed some new light on it. I haven’t used a vitamin C product lately but now I just may!

It’s quite a good ingredient to use frequently. My recommendation is to use it for a stretch like a month or two and then stop a month or two before resuming. Of course, some people may prefer to use it all the time.

I’ve heard a lot of good things about Vitamin C and its effects on the skin. However, there are many facts you brought up here that I have never heard about. Like when you said that Vitamin C has the ability to increase collagen production and that it can irritate sensitive skin. After reading your post, I now have more reasons to take Vitamin C supplements because of its many health benefits and its good effect on the skin. Not only can it minimize dry skin but it also provides UV protection and is very safe to use. This is post has been very helpful, thanks.Kim Dolores last post is: Collagen Types You Should Know About

Thank you for this very comprehensive article on Vitamin C. I have heard many good things about Vitamin C for the skin as well. I am particularly interested in its ability to fade dark spots or uneven pigmentation. Do you know if vitamin c is indeed effective for pigment related skin problems?

I love the skin care I use. It has Vitamin C, A, E and Glycolic Acid in a base of organic pharmaceutical grade aloe. Exfoliant is a daily leave on exfoliant and delivers the pH of 2.1 to 2.3. No parabens, fragrance or animal testing. $15 two week trial kits available for all skin types. Formulated by a Board Certified Plastic Surgeon and Made in USA.

I once watched a doctor on TV cautioned that too much oral supplementation of Vitamin C can deplete iron. A case of something beneficial going bad. So like any health supplements, it is better to stick to the recommended daily intake of vitamin C supplements to enjoy its full benefitsRose last post is: Idol Lash Review – Is There Clinical Proof That It Works?
